Why do clients obsess over the logo size but miss the fact that the checkout button doesn't work? It’s not incompetence. It’s the Bike-Shedding Effect (Parkinson’s Law of Triviality).
Cognitive Load and Decision Fatigue
Clients often provide feedback on the things they understand easiest (colors, fonts, images) rather than complex UX flows, because the cognitive load is lower. They feel safe having an opinion on blue vs. red.
To break this loop, you need to guide their attention. Don't ask "What do you think?". Ask "Does this user flow solve the problem of X?"
"Specific questions yield specific answers. Open-ended questions yield chaos."
By framing the feedback session around goals rather than aesthetics, you shift the client's mindset from "Art Critic" to "Business Partner."
